Three Words For Getaway Day: Soggy, Sloppy And Snowy

Passengers wait for a BoltBus to arrive during a light rain, Wednesday, Nov. 27 in New York. A wall of storms packing ice, sleet and rain could upend holiday travel plans as millions of Americans take to the roads, skies and rails for Thanksgiving.

While those in the western half of the nation will mostly enjoy fair skies on this Thanksgiving Eve, we regret to repeat that for millions of Americans east of the Mississippi it's going to be a messy busiest-travel-day-of-the-year (otherwise known as Getaway Day).

"Heavy snow is forecast from the Tennessee Valley to western New England, with freezing rain possible across the Appalachians and western Mid-Atlantic into the interior Northeast through Wednesday. Meanwhile, heavy rainfall is forecast across parts of the Mid-Atlantic and Northeast."

So the standard rules apply: If you don't have to be on the roads, it's best to stay home; if you do have to travel, leave early; and if you're flying, check with your airline about delays. (Note at 10:30 a.m. ET: As you'd expect, FlightAware says cancellations are starting to accumulate at airports in Philadelphia, New Jersey and New York City.)

Our friends on the All Tech Considered blog also offer this tool: A "real-time map" that combines weather and flight data to show "which airports are being struck by storms, the number of delays and cancellations, and graphs [of] flight destinations and the chances they'll actually make it on time."

Meanwhile, if you're planning to turn on the TV and watch Thursday's Macy's Thanksgiving Day Parade, you should know that strong winds may ground the iconic balloons. According to The Associated Press, that's only happened "once in the parade's 87-year history, when bad weather kept them from flying in 1971."
